12 spokes are limited to mid 30's mm of excursion, which is more than most motors are capable of anyway.

Well I'm talking about spaced spiders which offer more cone and coil control and many more spider options like the original tc sound basket(t3 now).. And they have a ton of woofers that offer 3+ inches of throw mow n days..

can gain a lil more rearward by boring the basket to 4.5" and using risers so the spider can actually drop below the basket. this is rarely useful cause most motors wont let you travel 35+mm rearward also most 8" spiders max out around 35mm b4 starting to damage them...

But you have problems with the cone slapping the spiders..

The 9" spiders offer in the 30 prettly linear the 10" have nearly 50mm each way of excursion cap..

I just don't want to pack spiders togeter on one glue joint, ESP with these long 3"coils..

It's just a preference when I build a woofer I'm going to space my spiders..

Don't you mean the Fi owned basket? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

3" of throw is approx mid 30's mm of xmax, and there aren't really a 'ton' of motors that are capable of this. If you are talking xmech, there are a decent amount of them out there, but for most applications xmech isn't an important factor. I dont recommend listening to a sub that is being pushed beyond its xmax potential, as that means it is no longer linear and will sound like ass. If you are building a sub with a motor capable of more than mid 30's, yes look into the TC style basket that Fi does indeed currently own the rights to. For most applications, a 12 spoke will allow plenty of excursion.

the 12 spoke is great for spl woofers a few sql woofers need the tc basket. the thing is getting full bl at 30+mm dosent happen on high bl motors such as spl subs. its all about a strong motor a tight gap and lots of power in a ported enclosure...

I can't remember who owns what..

Normally my head Is stuck in figuring out PLCs now n days..

Btw 3"s is 76.2mm so 38mm..

Nothing wrong with the baskets but I like the thought that for dynamic peaks you should have clearance..

If you ever used 3kw per driver tuned in the low 30s you will get some serious throw..

Using a large sealed box or ib it's even more important..

Btw demin how's the zcons?

No parameters yet?

Unless you use underhung or Xbl both designs can easily surpass 30mm Xmax and proform as god as spl drivers..

 

[audioholic 5,000+ posts]

If you are going for SQL, I wouldn't consider overhung motors anyway. But to each their own, Im a big fan of BL optimization, but not everyone is. Bl optimized>underhung>overhung... for SQL. To put it in simplified terms.

Even for peak transients, I wouldn't personally want to exceed xmax. But Im anal, I realize at those output levels my ears probably wouldnt recognize the difference between xmax and xmech, but I like setting a system up that remains within linear limits whenever possible.

Scott bought that basket during the TC fire sale IIRC, and I believe that means legally anyone else using it is well using it with out his permission. As for the Zcon's, I think they are quite bonkers.

 

As for parameters, they have been up since we released them for public sale: ZCON Series Sub Woofer

I like those kind. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Didn't eD attempt an underhung model with a top plate that appeared to be 8" tall?

They did. Some manufacturers rely on aesthetics and common knowledge, which I find to often be flawed. eD is a me-too company, I wouldn't look to them for any thinking outside of the box.

Ben Milne has never had an original thought in his head. Look at the company he owns now.

Ben is a piece of shit. Is that blunt enough?
